Cryosurgery, using liquid nitrogen at -196 degrees C, was explored for treating colorectal liver metastases in an experimental study of rat colon cancer and in a clinical investigation of patients with unresectable liver tumors. The viability of rat colon cancer isografts showed that while two or three freeze-thaw cycles were 100% effective in controlling established isografts and preventing is...

lipoid proteinosis is a rare hereditary metabolic disorder transmitted as an autosomal recessive trait. it is characterized by the deposition of an amorphous hyaline-like material (glycoprotein) in the mucous membranes, skin and various internal organs. cryosurgery (n2o) was applied to remove and reshape the lip lesions in a case of this rare syndrome. the patient was a 24-year-old female. cryo...

Cryosurgery was used in 100 cases with various lesions in the ear, nose and throat over a period ranging from early 1980 to the end of 1981. It was found to be a safe, convenient and can be done under a local anaesthetic in the out-patients department. Vasomotor Rhinitis was the commonest indication for cryosurgery in our series. Satisfactory results were also obtained in cases of Epistaxis, Ha...

OBJECTIVE This study evaluated the results of the use of curettage followed by liquid nitrogen spray cryosurgery in a number of solid or multicystic ameloblastomas of the jaws and the postoperative complications related to this treatment modality. STUDY DESIGN Thirty-six patients with solid ameloblastoma of the jaws were treated with curettage followed by cryosurgery. The cryotherapy consiste...

Cryosurgery is a treatment modality consisting in the destruction of tissue by the application of extremely low temperatures. This causes irreversible damage to cellular metabolism, leading to tissue destruction within minutes, a mechanism that may be beneficial when used in diseased tissues. Because cryosurgery is effective, simple, and easy to perform, it has been used in the treatment of les...

As a part of ongoing efforts to develop computerized planning tools for cryosurgery, the current study focuses on developing an efficient numerical technique for bioheat transfer simulations. Our long-term goal is to develop a planning tool for cryosurgery that takes a 3D reconstruction of a target region, and suggests the best cryoprobe layout. Toward that goal, a planning algorithm, termed "f...
